Description

The present invention relates to home furnishing articles and relates to

  particularly an embodiment of a

  shaped chair, preferably in a wood-based material.

  A chair conventionally consists of a base usually formed of four legs and ensuring the raised seating of a horizontal plate and a vertical rear plate. The

  first horizontal plate defines a seat on which a person

  it may sound on its bed and the second vertical tray defines a backrest against which the person sits supporting his back. Many efforts have been developed in recent

  years in order to give the chairs an aesthetic

  that, often respecting the evolution of society while

  being dependent on the spirit of their innovators.

  Research has also focused on different

  executions of a chair, generally aimed at modifying their structure so that the said chairs are stronger and more stable, they improve the comfort of the person sitting or

  again so that they assume various positions and / or functions.

  As; examples that will illustrate these different con-

ceptions of chairs, we will quote:

  - the "skate chair" described and represented in the

  French v. No. 1,224,752; the "seat" described and shown in French Patent No. 1,309,385; - the "improved multi-purpose seat" described and shown in French Patent No. 1,346,370;

  - the seats in removable elements and their means of

  The "seat made of cantilevered metal frame" described and shown in French Patent No. 2,301,203, the "removable seat formed in particular by an assembly of folded sheets", are described and represented in French Patent No. 1,576,499. described and shown in French Patent No. 2,424,006; -the "removable chair" described and shown in FIG.

  All the seat designs described in these patents have a major disadvantage in the sense that the factor

  aesthetics is neglected in favor of the functional factor, in particular

  as regards chairs made from wood.

  Also, based on this finding, the applicant conducted research that resulted in a new generation of chairs

  wood, capable of striking the right balance between

  the aesthetic factor and the functional factor while preserving the

  traditional components - safety, seat and backrest -

of a chair.

  For this purpose, the wooden chair of the invention comprising

  a base, a seat and a backrest, is remarkable in that

  the consists of two symmetrical side frames drawing the base and the support of the seat and backrest. These two

  The latter are advantageously formed by two horizontal struts

  tale and vertical respectively, connecting the two side frames and each composed by a set of flat crosses whose ends are adjusted in the form of tenons intended to be assembled by interlocking in corresponding mortises formed inside the two lateral frames, next to one

  the other on the internal faces of these.

  Besides the attractive and original appearance, the chair of the invention

  tion has many technical advantages and among them: - a reduced number of different

  reduced to two (a side frame and a cross-member), is particularly

  noticeably suitable for mass production of said chair, - easy assembly of the whole chair which does not

  limiting that to an assembly operation by interlocking

  poured in the two lateral frames (assembly possibly consolidated by gluing), is particularly indicated for a presentation for the sale of a wooden chair in the form of "kit"

  (packaging comprising two side frames and a series of

  verses), - an absence of accessories for holding, assembling or fixing the constituent elements together;

  - a possibility of dismantling the chair for the trans-

  port (in the case where the assembly of sleepers and frames did not operate by gluing); - a synergistic effect of the sleepers that form the trays of the seat and the backrest while bridging the two

side frames;

- etc ...

  According to a preferred embodiment of the invention, the aforesaid lateral frames each adopt the shape of a slightly oblique amount relative to the vertical, implanted at its base in a horizontal shoe and comprising, fixed cantilevered on its height in the half-plane having the obtuse angle formed by

  the pad and said post, at least one parallel horizontal spar

  leash to the latter. This spar and the amount portion rising

  above are preformed with mortises in which are

  lamon the tenons of the aforesaid sleepers forming the seat plate on the one hand, when they are assembled at their ends with the longitudinal members of two lateral frames and, the posterior plate

  on the other hand, when they are assembled at their

  mended with the portions of uprights rising above the seat.

  It is understood that the general shape of the chair of the invention is given by the profile of the side frame whose originality is accentuated, in this case by parts of the frame working cantilever and made according to the " process of two non-coplanar wooden structural elements, by penetration of a tenon into a mortise "described and illustrated in the application for

  French Patent No. 84.10005, filed in the name of the applicant.

  Thus, a variant of the invention is to fix on the amount of the frames two superimposed spars protruding in the same

  half plane. The lower spar comprises the mortises in the-

  which come to fit the tenons of the sleepers forming the

  seat and the upper spar serves as support for the arm of the

  Sitting The chair of the invention then plays the role of chair.

  Other features and other advantages of the pre-

  invention will become clearer on reading the

  following description, giving, by way of non-limiting example and in

  look at the accompanying drawings, an embodiment of a chair

  respecting the fundamental concepts of the invention.

On these drawings:

  FIG. 1 is a partly broken perspective view.

  of such a chair; Figure 2 is an enlarged view of a detail of the drawing

of Figure l.

  As shown in the drawing of Figure 1, the

4 2568116

  chair of the invention, referenced I as a whole, is constituted

  killed only from elements made of wood. It consists in particular of two symmetrical side frames 1 and 1 'each comprising an amount la, the' resting at its base on a shoe lb, lb 'and a horizontal beam lc, lc' fixed cantilevered on said

  amount to a predetermined height of the latter and in the half

  plane delimited by the obtuse angle "formed by the skate and the

  As. The shoe lb, lb 'ensures on the ground the maintenance of the amount la, the corresponding implanted in, in a slightly oblique position relative to the vertical which, determined by the greater or lesser opening given to the angle b, provides better comfort to the person sitting on the chair I. The two side frames 1 and 1 'are interconnected by means of flat cross members 2a and 2c which are preformed to their

  two extremities in the form of a C whose two branches

  two tenons, as can be seen in more detail in the drawing of Figure 2. The two tenons of the C of these sleepers 2 then come to fit, as shown by the arrow E, in

  corresponding mortises in the above-mentioned lateral frames

  1 and 1 'and in which they can be held by gluing. The presence of the two tenons at the ends of the sleepers 2

  considerably limits the game of the assembly obtained.

  Thus, the cross members 2a, the ends of which are assembled with the two portions of uprights 1a, 1 'rising above the longitudinal members 1c, 1c', define a perforated plate (the sleepers preferably being spaced apart from one another ) forming file A

  of the chair I, and the cross bars 2c whose ends are joined together

  with the two longerons lc, lc ', define an additional plateau.

  re-forming seat C of the same chair.

  The invention having been described and shown above has been for disclosure rather than limitation. Also, it is possible to make, in the embodiment of the above embodiment, numerous variants aimed at improving or modifying the shape, the dimensions, the constituent material of the various elements of the chair but not altering in any way the original characteristics and

  of the invention, taken in his mind and in his

widest pects.

  As has been stated at the beginning of this memo, the chair of the invention finds a particularly interesting application

  for marketing in the form of "kit".
